Systems
DRAFT SCOPE The subcommittee and its working groups and task forces are responsible for treatment of all matters relating to data acquisition, processing and control systems within substations. These systems include transducers, Intelligent Electronic Devices (IEDs), Human Machine Interfaces (HMIs), and communication networks. These matters include the low-level interfaces to and protocols communicating locally and remotely with these systems. Cyber and physical security and the environmental phenomena that can adversely affect these systems are included. The subcommittee supports similar work being done in other standards development organizations working on smart substations.

So, Where’s the Model? 11
IEC 61850-90-3
• Using IEC 61850 for condition monitoring diagnosis and analysis – GIS – Transformer – LTC – Underground cables – Transmission lines – Aux power systems
• Second draft out for comment 9/20/2013
12
A Perfect Storm
• Recent visit to an American client implementing transformer monitoring
• PEAC 2014 case study on transformer monitoring – Canadian utility paper on
implementing transformer monitoring
• NERC CIP v5
13
A Tale of Two Monitoring Systems
• Both have dedicated data concentrators to collect data from monitoring IEDs – One in the control house – One in a transformer cabinet
• Both have fiber to transformer – One has a cable of two strands of fiber – One has a twelve strand cable terminated to patch
panels • Protocols
– Both use DNP3, one TCP/IP the other serial – One also uses Modbus TCP
14
A Tale of Two Monitoring Systems • Integration
– One sends data back to SCADA with a local HMI for transformer alarms
– One will only be polled by SCADA so data can get to a historian
– One uses local I/O and IEDs, the other uses just IEDs – Both collect data from gas monitor, temperature monitor,
bushing monitor; one adds an LTC controller • Security
– Both provide no security between the control house and transformer cabinet equipment
– One is disconnected because of NERC CIP concerns
15
Observations
• Both implemented transformer monitoring systems as mini-SCADA systems (mini-SAS)
• Both see transformer monitoring as non-critical from a security standpoint – Isolated networks – No understanding of how their systems can be
leveraged for cyber and/or infrastructure attacks
16
Observations
• NERC CIP v5 BES Cyber Assets – Cyber Assets that, if rendered unavailable, degraded,
or misused, would adversely impact the reliable operation of the BES within 15 minutes of … compromise.
– Discrete assets can be combined into systems whose impact is designated as high, medium, or low impact based upon specific functions or point system
• Neither used concepts or processes in IEEE C37.1 to create their designs
• Use of Modbus is still prevalent in condition monitoring devices
17
What is missing or can be improved ? On-line Condition Monitoring Value for Present and Future Grids
• Standards or guides – Utilities have standards developed in IEEE PES
SUBS to help with condition monitoring system design and device requirements
– IEC 61850-90-3 is developing models – Monitoring systems being installed today can
benefit from IEEE Std C37.1 – Vendors can use requirements to add or improve
functionality in their devices
